In Bangladesh, 152 soldiers have been sentenced to death by a special court for their role in a mutiny four years ago.

The convicted are among some 850 people accused of murder and arson at the headquarters of the countryâ€™s border guards. Four of those charged have died during the trial while 20 others are on the run. The rest remain behind bars.

Some 4,000 people have already been found guilty of involvement in the mutiny, all in mass military trials. They have been jailed for up to seven years.

Began principally because of resentment over pay and conditions - the average border guard at the time of the mutiny earned about $70 (Â£50) a month, equivalent to the wages of a low-ranking government clerk

Exactly why it became so violent - with senior officers and their family members shot in cold blood - is unclear. One theory is that resentment against the officer-class had reached boiling point

The mutineers stole around 2,500 weapons and broke into an annual meeting of top border defence officers before shooting themThe case is believed to be one of the largest of its type in the world, with hundreds of witnesses called for the trial that started in January 2011

The uprising briefly threatened to overthrow the newly-elected government of Prime Minister Sheikh Hasina in a country with a history of military-backed coups

Soon after the uprising was crushed, the government announced it was changing the law to allow mutiny to be a capital offence
